Title: Signal reader
Inventor: ARAI KAZUO
IPC: G11B5/52
Filed: 1987-09-21
Abstract: PURPOSE:To obtain a thinned signal reader by providing a shield material indicating a Meissner effect between a signal reading head and a motor for driving a rotating cylinder for rotating the head. CONSTITUTION:A fixed cylinder 11 is fixed to a mechanism chassis and a rotating cylinder 2 is rotated by the motor 3 using a shaft 8 in common. This motor 3 is constituted of a printed board 12 fixed to the fixed cylinder 11, a motor coil 5 disposed on the printed board 12 and a rotor consisting of a rotor yoke 7 and a rotor magnet 6. The shield material 4 is fixed between a part for generating a magnetic flux by the motor of the motor coil 5, the rotor magnet 6 or the like on the fixed cylinder 11 and the head 1 by a bonding agent or a screwing. Since this shield material 4 is made of the material indicating the Meissner effect, it does not pass the magnetic flux to operate as a complete magnetic shield plate. Accordingly, the thinned device by approaching the rotating cylinder 2 to the motor is obtained.

Title: Magnetic recording and reproducing device
Inventor: SAITO KIYOSHI
IPC: G11B27/10
Filed: 1988-09-22
Abstract: PURPOSE:To reduce retrieval time by applying high speed retrieval a tape time position based on recorded time information when time information is recorded on a magnetic tape and applying high speed retrieval of the tape time position based on the tape running time information when no time information is recorded. CONSTITUTION:When the time information is recorded on the magnetic tape 1, high speed retrieval of the tape time location is applied by using the time information recorded on the magnetic tape 1. On the other hand, when no time information is recorded on the magnetic tape 1, a signal representing no time information is sent from a time information storage means 11 to a comparison means 13. The comparison means 13 receives the signal to switch the circuit so that the output of a tape running time calculate means 17 is inputted to the comparison means 13. Then the comparison means 13 compares and collates the tape running time with the tape time position in the retrieval time information set to a retrieval time setting means 12 to execute the high speed retrieval of the tape time position. Thus, the retrieval time is reduced.

Title: Sealed food container having deoxidating function
Inventor: MIHARA KAZUTOSHI
IPC: B65D81/26
Filed: 1987-09-21
Abstract: PURPOSE:To permit a full, speedy deoxidating action and thus obtain a sealed food container in which the deoxidating agent will not intrude into the contents by sealing the container using a packaging material permeable to oxygen but impermeable to water, with a deoxidating agent containing metals and wet substances giving off water by heat in a heat sterilization process added to its contents. CONSTITUTION:A food container is sealed using a packaging material permeable to oxygen but impermeable to water, with a deoxidating agent containing metals and the wet substances giving off water by heat in a heat sterilization process added to its contents. The wet substances give off the water contained therein by heat in the heat sterilization process, thereby starting deoxidating reaction with the metal components. The oxygen in the head space portion of the sealed container and the residual oxygen in the contents permeate the packaging material into contact with the metal components for removal by the deoxydating reaction and the transfer to the contents of the metal ions formed in the water released from the wet substances is hindered by the packaging material, not affecting the contents. For example, the packaging material is formed into a small bag, packed with deoxidating agent and sealed, and this small bag is either placed in the contents of the container or attached to a perdetermined location thereof.

Title: Clothing drier
Inventor: YAGI KEIJIROU
IPC: D06F58/28
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce a burden for operation, to lower the cost of a product and to save using power by providing an opening part with an openable/closable opening/closing lid capable of exhausting circulation air to the inside or the outside of a device and automatically opening this opening and closing lid by detecting the variation of humidity in the circulating air. SOLUTION: At the time of drying operation, heat generated by a heater is guided as hot air into a drum by a thermally exchanging fan to heat matter to be dried to evaporate moisture. In a drier like this, an exhausting lid 17 which can be opened and closed to a part of a circulating air duct is provided on the front surface of a clothing drier. The lid 17 is provided in the state of being freely rotatable with a rotation supporting point 17a as a center and is normally kept in a closed state by a coil spring. However, in the case that humidity detected by a humidity sensor, etc., provided in the circulation air duct becomes a prescribed value, an electromagnetic solenoid 19 is energized to open the lid 17 through an arm 20.  Thus, humid air is exhausted from the circulation air duct at the time of entering the decreasing rate of drying, thereby the deterioration of drying efficiency is prevented.

Abstract: PURPOSE:To finish the surface of a molding beautifully in order to improve the commercial value and realize the automatization of a compression-molder after injection molding by a method wherein an air nozzle is installed on a mold so as to leave a molding only either onto the movable side or onto the fixed side of the mold when the mold of a molder is open. CONSTITUTION:Molten molding material is injected between the cavities 23 and 24 of molds 2 and 6, which are closed by the predetermined mold clamping force. When the molding material cools down and solidifies itself, compressed air is fed from the inlet 14 of the one air feeding port 13 and, in succession, the mold opening action is started. The compressed air flows in the interfaces between the fixed side cavity plate 2 and a molding, runners and a ring gate so as to forcibly release the molding between the cavities 23 and 24 from the fixed side cavity plate 2 in order to leave the molding onto the movable side cavity plate 6. When the mold opening action comes to a stop, an unloader chucks a sprue 4 in order to smoothly release the molding from the plate 6 by feeding compressed air from the other air feeding port 21 so as to flow the compressed air in the interface between the movable side cavity plate 6 and the molding.
